The San Francisco 49ers have numerous notable free agents after this season wraps up, and Alex Boone is among the biggest. The left guard will likely miss the final three games of the 2015 regular season due to an MCL tear, but it is unlikely the injury will cost him in free agency. I imagine he could be one of the highest paid guards by the time his free agency comes to a close.
Some have wondered if the team will bring back Alex Boone, but all indications are that there have not been any real discussions about an extension.
